| 摘要 |
The present invention is directed to methods of sensitizing a human tumor cell with adenovirus E1A. The methods involve treating a human tumor cell by, first, introducing into the tumor cell nucleic acid encoding a polypeptide having adenovirus E1A activity, expressing the E1A active polypeptide in the cell, and then either contacting the E1A expressing tumor cell with a chemotherapeutic agent or irradiating the E1A-expressing tumor cell. The invention also provides methods of enhancing a subject's response to chemotherapy or irradiation by introducing into a subject's tumor cells nucleic acid encoding a polypeptide having adenovirus E1A activity, expressing the E1A active polypeptide in the cells and finally, administering either a chemotherapeutic agent or irradiation. The invention also provides a method of treating cancer.
